Further fobj ects 'ofi lthe invention* are to 'f Y provide aiy sashf fastener.l ofasi'm'ple; Vipractical construction, which will be rugged, durablej Y i'rOeliiIig the-'levier oiifthe., pin 1 117. 1

and rr` efficient Ain use; which .is" well:V suited to the requirements of economical manufacv ture, and which may be conveniently manip'- ulated to Vshift the same into or outV of operative position. Y

With the above noted and other objects in view, the invention consists in certain novel features of'construction and combina# tions and arrangements of parts, as will be more fully hereinafter set forth and pointed out in the claims. vThe invention mayv be more fully understood from the following description in. connection with the accom-- panyingdrawings, wherein-V l Fig. 1 is a fragmentary perspective view showing a portion of a window frame with a pair of sliding sashes mounted therein, and one of my improved window fasteners in position.

Fig. 2 is a window fastener being shown in section and in its inoperative position.

f Fig. 3 is aview similar to Fig. 2, butv transverse sectional detail view through the upper portion of one sash and the lower portion of the other sash, the

Y yFig;l 4L is.: a top plan view of the fastener. "Int-he drawingsl haveusedthe reference 4character '-.10`fto vdesignate awindow iframe with in whichfare'mounted-an uppersliding 4`windowl Afastener of the p resent invention is IsashY 11 'and aflower slidingrsash v12. The

With the wedge spring pressed into engagement withthe Vupper sash, it willbe seen thaty sliding movement of this sash in a downwarddirection is effectively blocked. The

greater the pressure which is .appliedl in an attempt to effect such krelative movement,

lIt will be apparent that the fastener when in use will preventnndue vibration of the two sashes, particularly if a fastener is used* at each side of the window. The function pf' thedevice as ra lock has already been set orth.

Obviously various changes and alterations `might be .made in the general form and arrangement of parts described lwithout departing from the invention. Hence I do not vwish to limit myself toy the'details set forth, but shall consider. myself at liberty to make such changes and alterations as Y fairly fall within the spirit and scope of the appended claims.v v

I claim:

l. In a window fastener, a base'plate, an angular lever pivoted intermediate its ends labove the base plate, a spring urging the lever in one directionabout its fulcruin, and a swinging -bailcarried by the lever engageablel with the base plate and acting `as a V*prop to limit the lrocking movementof the lever under the in-iuence of the spring.

2. A' window *fastener including I a Vbase plate, an angular lever including depending side flanges pivoted between the ears, a

vcoiled torsional spring encircling the pivot pin and urging the lever in one direction, a

`tail piece on the lever for manually rocking the same against the actionV of thespring,

and a second pair of ears-between which the iianges are adapted to be wedged to lock the lever against movement under thefimpetus Vof the spring.

3. A window fast-ener including a base coiled ktorsional spring encircling the pivot pin and urging the lever in one direction, a

tail piece on the lever forl manually rocking VYthe same against the actionof thefspring,

and a swinging bail mounted rin the fianges and engageable with the basefplate,-oper able to limit swinging movement of the lever s under the influence of the spring.
